Rep. Maxine Waters, D-Calif., tweeted "Bye Felicia" to Secretary of State Rex Tillerson Friday afternoon after declaring the top diplomat's strategy to handling Russia had failed.

"Tillerson's plans are backfiring. Russia sanctions still in place, State is in shambles, & he discovered his boss is a moron. Bye Felicia!" Waters tweeted.

The term "bye Felicia" was used in the 1995 movie "Friday" before becoming a popular phrase.

"Bye Felicia is a dismissive term which can be used in a number of different contexts," according to an entry on Dictionary.com. "Most simply and frequently, it is used as a cold way to bid someone farewell."

On Wednesday, NBC reported that Tillerson was unhappy working under President Trump in July and threatened to quit during a trip to Texas for his son's wedding.

The report also stated Tillerson called his boss a "moron."

Tillerson denied on Wednesday that he had threatened to leave his administration post, but dodged questions about whether he called Trump a "moron." A State Department spokeswoman later said the insult was never made.

Tillerson and Trump have continued to clash over foreign policy. After Tillerson said the State Department was working toward direct talks with North Korea, Trump tweeted that the approach would not bring about progress.
